Ada Twist, Scientist! Ada the scientist is a little girl of color who asks her parents a zillion questions. She is full of energy, makes messes all over and is burning to explore the world around her fueled by one simple question: WHY? Ada’s parents (who are classy and well-dressed) feel frustrated with Ada while also trying to nurture her nature. As a parent to a super curious 3.5 year old who asks 400 questions a day, this book is also a great reminder for me as a grownup. Rock on Ada. You’ve become a fast favorite around here.
